I don't see how a single device at the meter (thinking smart meter here) can ascertain what devices are being used in the home to profile anything. The meter can only read the current going through it (well maybe it can do inductive vs resistive loads, too), so there's not much it can do to determine that it's installed at a home with a hot tub and a band saw. It can determine that the energy draw generally is higher in the morning and early evening (furnace) and has a higher average level in the evenings in the winter than summer (lights). However, being able to do the things that TED can do seems highly unlikely. I would love to be able to do something like TED, but my interest level has never exceeded the budgetary hurdle for that type of monitoring.
